    DUN vs. TCP/IP priority

    I'm running Win98 SE (v.4.10.2222 A) with a Comcast 2-way cable modem connection that, when I'm lucky, works a few hours per day. Accordingly, I have to maintain a dial-up account with a local ISP. When the Comcast connection fails and I'm forced to use the dial-up account, I'd like Windows to recognize when the Comcast connection returns and use that instead of the dial-up.

    Many searches through the MS Knowledgebase and other online technical resources failed to uncover any useful information on this topic, however, one of the MS people at a recent TechNet event told me that DUN will always take priority over TCP/IP. Having overheard my conversation with the MS tech, the fellow next to me contradicted that information, saying there was a way to make Windows recognize (and select) the faster connection, and sent me to this site for instructions on how to do that:
    <A target="_blank" HREF=http://cable-dsl.home.att.net/#Dialup>http://cable-dsl.home.att.net/#Dialup</A>

    But I dunno, after reading this, I'm not sure it's the right solution. Any thoughts or comments would be greatly appreciated.

    Thanks,

    Re: DUN vs. TCP/IP priority

    What I saw on the site that you provided a link to was a way to force certain connections - such as certain websites - to use the dial-up connection. This isn't really what you want. This tactic doesn't solve your problem because it only adds a network route while the connection is active.

    If it's browsing the Internet you're primarily concerned about (although this affects all Internet related connections), open Internet Explorer, click on tools, then click over to the tab labeled Connections. There you should see the following options:

    {li]Never dial a connection
    Dial whenever a network connection is not present
    Always dial my default connection

    You want the second option checked. Also, check the settings and LAN Settings buttons and make sure that "Automatically detect" is selected.

    Lastly, go to your Network Properties in the Control Panel, and check the properties of you network adapter -> TCP/IP (not the dial-up adapter). There is a check box on one of the tabs (sorry, I don't remember offhand and I'm on an NT box at the moment) that says "make this the default protocol" or similar. That should be checked for the network adapter and nothing else.

    It's not perfect but that's about as good as it gets short of going to something along the lines of Windows 2000/XP, which handle networking connections much better. Maybe, just maybe, that will help out some!

    Thanks, Mark. That looked like more of an IP specific solution to me, too.
    As per your reply, I've checked the 'Automatically detect' option in LAN settings.
    Here's hoping it's the missing link. <g>

    Appreciate the help.

    I hope that it works. I've never had the problem you are experiencing, but I understand the process. Is it that your cable modem provider's service bottoms out without warning?

    Either way, I thought I should mention that IE will *not* automatically detect settings if there is another IE instance or window running. You have to close them all down for a few seconds so that it will auto-detect again.

    Keep us posted on your progress, hey? I'd like to know what happens. And BTW your signature/quote is the BOMB. <img src=/S/clapping.gif border=0 alt=clapping width=19 height=23>
